The science of dog hair
Cleaning up dog hair is an ongoing job. Dogs moult a lot in spring because their coats are exposed to more daylight. It triggers a reaction in the hair which makes it fall out. In autumn, less daylight has the same effect – this time making way for the thick winter coat.
A dog’s coat contains a mixture of hair types: longer protective guard hairs and an insulating undercoat. It grows in cycles all year round. There are three different stages: Anagen (growing); Catagen (stopped growing); Telogen (dying and moulting). So dogs can continually be losing dead hair throughout the year.
